Hello everybody,

I tried converting a 3D tetra/prism mesh (generated with gmsh) of a simple cylinder from msh to xml using NekMesh. The domain has periodic boundaries along the cylinder axis. However, I receive the following error:

Orientation of triangular face (id = 113069) is inconsistent with face 3 of prism element (id = 55392) since Dir2 is aligned with Dir1. Mesh setup needs investigation
terminate called after throwing an instance of 'Nektar::ErrorUtil::NekError'

I've seen a similar post from May 12th, where it was suggested to try the peralign option, so I used:

NekMesh -m peralign:surf1=700:surf2=800:dir=z:orient CylReD3900.msh CylReD3900.xml

with no success. The two surface IDs 700 and 800 of course refer to the periodic boundary faces.

I attached my msh file and appreciate any help.

All the best

Alex
